APPLICATIONS

Over-temperature/over-load protection:

• Telecom

- Telecommunications infrastructure

DESCRIPTION

The component consists of a high-performance PTC ceramic

disc mounted in a lead-frame for direct soldering onto a

printed-circuit board (PCB) or substrate.

PABX

- Set-top box

The ceramic is soldered to the leadframe by a local reflow

process, during which the solder layer is melted to the

metallized ceramic surface using a low residue flux.

MOUNTING

With a flat pick-up area = 30 mm²the PTC thermistors are

suitable for processing on high speed automatic insertion

equipment.

MARKING

Typical soldering

• All TWIN Vertical SMD PTC’s are marked with the last

3-digits of the type number (BCxxx) and a date code

TWIN Vertical SMD PTC Thermistors

SOLDERING CONDITIONS

This SMD thermistor is only suitable for reflow soldering, in accordance with JEDEC J-STD-020. Soldering processes which can

be used are reflow (infrared and convection heating) and vapour phase. The maximum temperature of 260 °C during 10 s should

not be exceeded and no liquid flux should be allowed to reach the ceramic body.

Typical examples of soldering processes that will provide reliable joints without damage, are shown below.

HANDLING PRECAUTIONS

Because of the nature of PTC ceramic material the component should not be touched with bare hands, as the residue of

perspiration can influence component behaviour at high temperatures.

Handling forces applied to the centre of the component should be limited to 20 N vertically and 5 N horizontally in non-soldered

condition. These forces should not be exceeded during the handling, transportation and packaging of the soldered product.
